<p>I am going to take the Oct Math II, and just did the Barron's diagnostic test with 2 wrong. How different is the diagnostic test from the model practice test? I know the practice test is harder than the real one. Shall I go over all Barron's review content before model test? Thanks for the post.</p>
<p>I’ve only used Barron’s books for AP so far, but they have always been much harder than the actual tests. Their diagnostic tests I think are about the same as their regular tests, maybe easier. I’d suggest reviewing chapters that you know you have to review - if you don’t really need to review anything (i.e. you missed two because of stupid mistakes), then just go ahead with the normal practice tests.</p>
<p>Thanks for your reply.</p>
